Description Murray McAllister 2014-06-30 03:35:30 UTC
A flaw was reported in D-Bus's file descriptor passing feature. A local attacker could use this flaw to cause an invalid file descriptor to be forwarded to a service or application, causing it to disconnect from the bus, typically resulting in that service or application exiting.

It is reported that versions 1.3.0 and newer are affected.


Red Hat would like to thank D-Bus upstream for reporting this issue.
